I am assuming that you are looking for the length of one of the sides of the right triangle.
Let's label the sides of the triangle as follows:
The hypotenuse of the triangle is the side opposite the right angle and we will label it as "c".
The side adjacent to the angle of 27° is "a".
The side opposite the angle of 27° is "b".
Given the angle of 27° and the length of the hypotenuse as 21, we can use trigonometric ratios to find the length of one of the sides.
Using the cosine ratio, we have:
cos(27°) = adjacent/hypotenuse
cos(27°) = a/21
a = 21(cos(27°))
a ≈ 18.3
Therefore, the length of the side adjacent to the angle of 27° is approximately 18.3 units (rounded to the nearest tenth).
Find the value of x. Round to the nearest tenth of a unit.
